After being offline for some time, upgrading the Linux distro and 
kernel, pulling latest v4l-dvb I now can consistently tune to all 
channels in DVB-S and DVB-S2 mode. So maybe a STB0899 frontend fix for 
the TT-3200, I didn't check all the commits in between the 2 releases I 
was using.

So whilst a late reply I think this one if finally sorted for the TT-3200.

Thanks for your support in getting this to work.
